BOOL_TO Conversions
IEC Operator: Converting from type BOOL to any other type.
Syntax for a BOOL_TO conversion operator:
BOOL_TO_<data type>
For number types the result is 1, when the operand is TRUE, and 0, when the operand is
FALSE.
For the STRING type the result is ‚TRUE', when the operand is TRUE or ‚FALSE' when the
operand is FALSE.
Examples in IL:
(* Result is 1 *)
(* Result is 'TRUE' *)
(* Result is T#1ms *)
(* Result is TOD#00:00:00.001 *)
(* Result is D#1970-01-01 *)
(* Result is DT#1970-01-01-00:00:01 *)
Examples in ST:
i:=BOOL_TO_INT(TRUE); (* Result is 1 *)
str:=BOOL_TO_STRING(TRUE); (* Result is "TRUE" *)
t:=BOOL_TO_TIME(TRUE); (* Result is T#1ms *)
tof:=BOOL_TO_TOD(TRUE); (* Result is TOD#00:00:00.001 *)
dat:=BOOL_TO_DATE(FALSE); (* Result is D#1970 *)
dandt:=BOOL_TO_DT(TRUE); (* Result is DT#1970-01-01-00:00:01 *)
